There have been many books about space-flight, but this is the first illustrated, step-by-step presentation of the subject. In a manner that combines scientific accuracy with artistic skill, it depicts the various stages in the progress of astronautics, from the launching of the first unmanned rockets to the final establishment o a lunar colony. The forty-five illustrations (eight in full colour) provide a dramatic survey of the problems and possibilities of space-flight, and are the work of R.A. Smith, who has studied the subject intensively for more than twenty years and has considerable practical experience in modern rocket design. He shows how, by the correct use of science and engineering skill, the Moon may become a valuable permanent community in its own right, marking the beginning in its own right, marking the beginning of an entirely new relation between Man und his universe. The descriptive text is by Arthur C. Clarke, well-known for his books and television programmes on space-travel. He has twice been chairman of the British Interplanetary Society and, like R.A. Smith, has served on the Society's council since 1937.
